A royal corkscrew.

I've always been a fan of perfume corkscrews. These corkscrews were often found alongside button hooks & nail files and were produced in several different materials and often customized. It's not uncommon to find examples engraved with a monogram or family crest. This recent acquisition features a crown atop the letter R. Could this corkscrew have belonged to royalty? Possibly. If anyone has any information on the previous owner of this piece then let me know.
